Security: Given a scenario, secure SOHO wireless and wired networks Flashcards
You need to broaden the area to which a wireless access point (WAP) can transmit. What should you do?
a. relocate the AP
b. change the channel used by the AP
c. maximize power level setting
d. adjust the power level setting slightly higher
d. adjust the power level setting slightly higher
You need to implement a wireless protocol that provides maximum security while providing support for older wireless clients. What protocol do you use?
WPA (WiFi Protected Access)
WPA is designed to work with 802.11i while providing backward compatibility
WPA uses TKIP (Temporal key integrity protocol) for encryption
WPA2 uses CCM (CCM Mode Protocol)
You want to ensure no unauthorized wireless access points are being established. What should you do?
Periodically complete a site survey
How would you protect against unauthorized Site Surveys?
- Change the default SSID
- Disable SSID broadcast
What is the purpose of MAC filtering?
To restrict the clients that can access a wireless network
This is no longer secure as MAC addresses can usually be found with a network sniffer
What’s the easiest way to change a local password on a Windows 7 Ultimate computer?
Press ctrl+alt+del and select “Change a Password”
Where should wireless antennas generally be placed?
As far away from exterior walls as possible, or close to the center of a building
What should the default network permission position be?
Implicit deny
What is an evil twin in network security?
An access point with the same SSID as the legitimate access point
_____ is a method of discovering 802.11 networks by driving around with a laptop and looking for open wireless networks
War driving
To protect against this:
- Change default SSID
- Disable SSID broadcast
- Configure network to use authenticated access only
- Configure the WEP protocol to WPA
- Implement WPA2 instead of WEP
- Reduce access point signal strength
